Roger Wagner’s Assembly Lines articles originally appeared in Softalk magazine from October 1980 to June 1983. The first fifteen articles were reprinted in 1982 in Assembly Lines: The Book. Now, for the first time, all thirty-three articles are available in one complete volume. This edition also contains all of the appendices from the original book as well as new appendices on the 65C02, zero-page memory usage, and a beginner’s guide to using the Merlin Assembler. The book is designed for students of all ages: the nostalgic programmer enjoying the retro revolution, the newcomer interested in learning low-level assembly coding, or the embedded systems developer using the latest 65C02 chips from Western Design Center.
